PREFACE 



CATALOGUE literature is an essential part of the working library of every practicing 
engineer and purchasing agent. Corporation officials, designing and consulting special- 
ists, industrial managers, and engineers all alike must refer constantly to engineering 
and machinery catalogues. And this for the essential reason that nowhere else can they so 
quickly discover the equipment available for their purposes, with exact details of its applica- 
tion. With a complete catalogue library at hand preliminary plans may often be settled at a 
single conference. All the reputable markets for the equipment desired may be tested by 
the same day's mail — but only if the full complement of catalogues in that particular field is 
on hand and accessible. 

Millions of dollars are now expended annually by individual manufacturers in preparing 
and distributing these valuable and thoroughly practical trade catalogues. The difficulty is to 
insure, first, that they reach the hands of the right persons, and, next, that they are preserved 
in the right place for reference at the right time. 

Herein lies the one great service which THE ENGINEERING CATALOGUES are de- 
signed to supply. It brings into a single volume, compactly assembled, that which other- 
wise would be diffused through hundreds of pamphlets, scattered over many shelves, perhaps 
to be found only with the aid of reference to a card index. It brings into consecutive pages, 
standardized in arrangement, in its most concentrated form, information otherwise spread 
through a multitude of booklets varying in shape, form, date, and order of contents. By means 
of a single reference index, it enables any item to be located immediately, either by its gen- 
eral mechanical classification, its trade name, the name of its manufacturers, or the place 
of its production. It does what no single catalogue could do — what nothing else except an 
individually and laboriously prepared reference list would do: it displays at a glance all the 
products of any given sort, affording the user of the volume complete opportunity to make 
intelligent selection of the equipment best suited to his special need. 

The volume is as serviceable and as eesy to consult as the dictionary, as up-to-date as 
the telephone book. It is as concise as the encyclopedia. With the co-operation of the man- 
ufacturers interested, it may be made as comprehensive as the city directory, and as author- 
itative as the engineers' pocket-book. It is to the collection of individual catalogues what the 
official railway guide is to the rack of multitudinous time-tables. It not only furnishes the 
consultant exact information on the point to which he has a clue, but it puts before him 
invaluable knowledge upon allied topics, which, without its aid, might have remained hidden 
from him, even their existence being unsuspected. 

To the user, the sum of these conveniences is so great that in fields where these gen- 
eral catalogues have been introduced they are fast becoming the standard authority of buyers, 
the guide most frequently resorted to in framing specifications. 

To the manufacturer, they offer the certainty that his products will be placed under thr 
buyer's eye, that he will have fair consideration, an equal hearing on an equal footing, with 
every competitor. His opportunity to bid will not depend upon the chance of his special 
individual catalogue having been mailed, received, kept, remembered and consulted. The index 
automatically calls him to the buyer's attention whenever and wherever the kinds of product 
in which he deals are sought or being considered. And, beyond this, it secures him notice, 
for possible future advantage, when other kindred matters are being looked up. 

The further argument in favor of THE ENGINEERING CATALOGUES is financial. 
Their distribution insures the preservation and the effective use of individual catalogues. These 
are always expensive to prepare, and m'any must be wasted to insure a very few reaching the 
hands from which productive business may be expected. Centralized manufacture of THE 
ENGINEERING CATALOGUES vastly reduces the cost to each subscriber. The same cir- 



a-r^^^ 



culation for each manufacturer may thus be secured at a fraction of the outlay he would 
otherwise incur. And there is no waste circulation. Every copy goes into the hands of a po- 
tential customer, and every copy is preserved and consulted. On the inquiry it stimulates, fur- 
ther business may be sought with every assurance of maximum possible result. By the interest 
it excites and the permanent guide it establishes, the more detailed individual catalogue a 
manufacturer may supply is assured personal attention and careful consultation. 

The field to which this edition is devoted is perfectly definite and compact. It is the 
field of power-plant installation, management, and superintendence. The purpose of the pub- 
lishers and editors is to make every entry serviceable to the power-plant designer, owner, 
and operating official. The purpose is also to place every copy in the hands of a carefully 
chosen individual who has a buying interest in the apparatus of every advertiser. 

On this perfect reciprocal service THE ENGINEERING CATALOGUES base their 
strongest claim for co-operation and support. 



INTRODUCTION TO 

SPECIFICATION DIGEST 



IN presenting this digest to the public a word of explanation is needed, as the form and 
scheme of the Digest are somewhat unusual. 
The Specification Digest may be described partly by what it is and partly by what 
it is not. 

It is an aid to avoidance of mistakes of omission and commission, and a saver of time. 
It is not a model specification. 

It is not an attempt to make one specification which shall fit every conceivable case. 
Such specifications have been made, and while they are useful to beginners in engi- 
neering work, they are really pitfalls for the unwary because they cause the uninitiated to 
follow blindly along paths that lead into all kinds of unforeseen troubles. 

What the Specification Digest Does 

The Specification Digest does not attempt the impossible task of telling readers what 
to specify, and how to specify the requirements of a series of unknown problems. The whole 
idea is preposterous. A specification contemplates specific detailing of requirements with : — 

First, A definite knowledge of the problems to be solved. 

Second, A knowledge of the properties, at least of the appliances it is intended to use. 

The more complete the knowledge of the problem, the more complete may be the 
solution; and the more perfect the knowledge is of the properties and possibilities of the 
appliances and materials, the more complete will be the solution. 

A brief discussion of the problems to be considered and the methods to be adopted 
will follow this preliminary matter, but the point cannot be too strongly emphasized that 
guess work is fool's work when engineering matters are to be settled. 

Exact data may be hard to get of probable requirements of plants or performance of 
apparatus, but sufficient correct information is obtainable by a little careful search in The 
Engineering Catalogues and technical press, or by inquiry among one's neighbors and friends, 
and best of all by thoughtful talks with representatives of manufacturers. The catalogues 
issued by manufacturers are, some of them, remarkable repositories of information, and in no 
other way can as good a knowledge of the inside workings of apparatus be obtained as by a 
careful study of these books. 

Here again general statements must be disregarded, such as "Most perfect design" or 
"Sufficient heating surface." They are like the pads in the old-fashioned tailor-made suits, 
merely put in to improve the general appearance but more deceptive than advantageous, 

1^ What the Specification Digest Is 

What then is the Specification Digest? It is a series of reminders of questions which 
must be answered fully and correctly in a specification, if the specification is to be specific 
and the purchaser is to get something approaching that which he expects to get when he 
sings the contract. 

As an example, consider the simple matter of purchasing a ventilating fan or blower. 
The usual procedure by the layman is to send a letter to a fan salesman and ask for an 
estimate on a fan to supply so many cubic feet of air a minute, and to be motor-driven or 
engine-driven as the case may be. 

The salesman comes and asks a lot of questions (the answers to which he must know 
before he can estimate) such as location, building of foundation, connections, etc., but un- 
less he is a remarkable man he does not ask the questions which vitally affect his price, 
such as the speed at which the motor is to operate, whether it is to be enclosed or open. 



whether speed regulation is desired, and if so, whether it is to be obtained by the most 
efficient method, or by the wasteful method of inserting resistance. 

All these and other similar topics he avoids because he wishes to keep his price down 
in order to get the order, and it is the buyer's business, he thinks, to see that the minor 
"frills" are watched for. 

This, then, is the object of the Specification Digest: — To place in the hands of every 
buyer the practical questions which must be decided when any single piece of apparatus or 
combination of pieces of apparatus is to be purchased. 

The questions which form the Specification Digest are not in the slightest degree the- 
oretical or unnecessary. They are many of them the fruits of expensive mistakes, and to- 
gether they represent many hundreds of hours which were wasted in discussions, but which 
might have been usefully employed if the questions had been fully answered in the speci- 
fications before the contracts were let. 

How THE Specification Digest Prevents Mistakes 

An example (by the way, a great many could be cited) of a dispute about an electri- 
cally driven pump which had been installed in a club under loosely drawn specifications may 
be illustrative. The architect called, in the electrical part of the specification, for a motor- 
driven triplex single-acting 6-inch by 8-inch pump, to be equipped with hand control and au- 
tomatic starter. The pump was to operate at 35 r.p.m. and was to be driven by an enclosed- 
type motor of or make. Pump to be equal to a Co. pump. Foun- 
dations were to be built by a contractor. Plumbing connections were to be made by the 
plumber. Everything to be complete and put into perfect working order. A fairly complete 
specification, one would think, much more so than is usual. 

Turning to our Specification Digest, however, we would find under electrically-driven 
pumps a number of additional points requiring definite specification, and it was just in con- 
nection with these points that over $100 worth of expert time was spent, and a final agree- 
ment reached whereby the Club deducted $135 from the contractors' bill, and accepted an 
outfit (or pair of outfits, to be exact), which were not what it really expected to get, and the 
contractor lost nearly $300. Where were the omissions? Look in the Digest. Nothing said 
about whether the pump was to have a cross-head or not; no mention made of relief valves; as a 
consequence, because the automatic valve remained closed, the cylinder casting broke the first 
time the pump was used; the starter would not regulate the speed as desired under light 
load conditions, and all the speed control was by inserting resistance in the motor circuit, thus 
wasting electricity continuously; no means hrd been provided for tightening the belt drive, 
and nothing had been said about the need of a raw-hide pinion to reduce the operating 
noise. An excessively high-speed motor was furnished, meaning greater up-keep expense and 
more wear, but nothing could be done about that, as no speed of motor had been specified. 

The motor and pump were not mounted on a single bed-plate, and the architect found 
to his dismay that the contractor planned to belt across a sort of passage-way in order to 
get a proper drive. The architect had supjjosed that the whole outfit would be self-contained, 
with an idler to keep the belt tight, but the bidder's ideas were quite different, and as no spe- 
cific mention was made, the bidder, of course, was in control, and what was more important, 
it was too late to change. There was no specific direction as to construction of foundation, etc., 
materials, or its depth, and it was only by personal persuasion that the architect could have 
a substantial foundation built, and even then he had to allow an extra for enamel brick around 
the foundation above the floor and a cap stone to top it. 

The bidder was not unfair; he had figured the job to get it, and if he had figured 
all the little extras required for first-class work someone else's bid would have been accepted. 
It should be borne in mind that this bid went to the electrical contractor, who in turn bid to 
the general contractor, who finally bid to the architect and owner; hence there was no chance 
for explanation or representation. 

As before stated, a hundred such disputes have actually arisen in the writer's own 
practice, and perhaps a thousand others have required discussion and explanation. Of equal 



moment is the enormous unnecessary waste of time, not only of the time of bidders, but 
that of purchasers, architects and engineers. Most of this would be avoided if the specifi- 
cations were complete and all the necessary details carefully and fully detailed in advance. 

The purpose, then, of the Specification Digest should be clear — to avoid mistakes of 
omission and commission and to save time. 

A Suggestion as to the Use of the Specification Digest 

Most specifications are based on other specifications previously made by the purchaser, 
or on specifications submitted by bidders. In either case, use these as a basis and take each 
part up with the Specification Digest, open at the item in question. For example: — if the 
specification is describing the feed-water heater desired, take up each of the sub-items, one 
by one, and see that every one of these is correctly answered in the specification. If this is 
done, even if the purchaser's judgment is not perfectly correct, the points will be brought 
to the bidder's attention, and he will either have to comply with the purchaser's require- 
ments or submit a definite alternative which the purchaser can accept or reject. The excuse 
of the writer for preparing this Digest is that an experience of fifteen years in active prac- 
tise of writing specifications, and planning and carrying out work, has shown such a col- 
lection of queries to be an absolute necessity if matters are not to be overlooked. 

Undoubtedly other points will occur to readers and other engineers, and information 
of such supplementary questions and items will be gratefully received. It is only by such 
mutual aid that a perfectly complete Digest can finally be evolved.

SPECIFICATION DIGEST 

POWER-PLANT EDITION 

A characteristic or composite isolated plant is taken as the model for this SPECiFiCATioisr Di- 
gest because it represents the most comprehensive installation conceivable. It includes all the 
elements of steam generation, electric conversion, distribution, refrigeration, ventilation, heating 
and lighting, elevator service, etc. 

Any other power-plant can be compared by selecting such of these elements as may be in- 
cluded in it, or, as explained on a preceding page, the replacement, extension, or addition 
of any part in an existing plant may be profitably studied by reference to the corresponding 
item in the SPECIFICATION Digest. 

For convenience, the Digest is arranged in eleven sections : General Clauses, Boilers and 
Stacks, Producers, Steamfitting, Steam Engines and Turbines, Internal-Combustion Engines, 
Dynamos, Electrical Equipment, Switchboards, Storage Batteries, Refrigerating Plant. The 
numbering used is intended merely to facilitate cross-reference or the definition of any item 
without the use of a long description.

STEAMFITTING 

The steamfitting section includes such a wide range 
of apparatus and work that it is the most voluminous 
in the Specification Digest. On account of the mag- 
nitude and special character of the items, Boilers (in- 
cluding setting and smoke-stacks) and Refrigeration, 
separate sections have been devoted to these contracts 
(see Sections 100 and 1000), and only their co-ordina- 
tion with the rest of the steamfitting work is taken up 
in the Section 300. 

Note: — It will be noted that several items in this as 
in other sections of the Specification Digest have been 
starred, or prefaced by an asterisk. These starred 
items may be specified, or preferably may be left for 
the machinery builder to specify. They are noted here 
to call attention to the necessity of definite knowledge 
on these points before placing a contract. 

The items to be considered generally in the steamfit- 
ting section of an isolated power-plant specification 
are as follows: 
300 General Outline of the Work:— 

1. Furnishing, Delivering and Erecting of 

Boilers (See Section 100). 

2. Steam, Water, Blow-Off and Smoke Con- 

nections TO Boilers. 

3. High- and Low-Pressure Steam and Drip 

Connections to Engines, Pumps, Com- 
pressors, Hot- Water Heaters, Etc. 

4. Blow-Off Tank. 

5. House-Heating System. 

6. Refrigerating Plant (See Section 1000). 

7. Drying Apparatus. 

8. Kitchen Apparatus. 

9. Injectors. 

10. Ejectors. 

11. Indirect Heating System. 

12. Direct Heating System. 

13. Ventilating Equipment, Including: — 

13-a. Fresh-air supply. 
13-6. Tempering coils. 
13-c. Air washers.

the whole work, it has been the writer's experience that 
sub-division results in better control of the work and a 
lower cost. For this reason the Specification Digest 
under the heading of Electrical Equipment deals with 
electric wiring and all matters directly connected there- 
with, but provides also separate sections on 

(1) Engines. 

(2) Dynamos. 

(3) Switchboards. 

(4) Storage batteries. 

As to electric fixtures there is no possibility of 
writing either a general specification or a specification 
digest. The selection of this work is a matter of taste.
